1. A patient has the following ABG results: pH 7.28, PaCO2 52, HCO3 24. Which
acid-base imbalance is present?
A. Metabolic Acidosis
B. Metabolic Alkalosis
C. Respiratory Acidosis
D. Respiratory Alkalosis
Answer: C
Rationale: The pH is low (acidosis) and the PaCO2 is high, indicating the respiratory
system is the cause of the imbalance.
2. Which hemodynamic parameter is the best indicator of right-sided heart
preload?
A. Central Venous Pressure (CVP)
B. Pulmonary Artery Occlusion Pressure (PAOP)
C. Mean Arterial Pressure (MAP)
D. Systemic Vascular Resistance (SVR)
Answer: A
Rationale: CVP reflects the pressure in the right atrium and provides an estimate of right-
sided preload.
,3. The nurse calculates the MAP for a patient with a BP of 90/60 mmHg. What is
the result?
A. 70 mmHg
B. 75 mmHg
C. 80 mmHg
D. 65 mmHg
Answer: A
Rationale: MAP = (SBP + 2DBP) / 3. So, (90 + 120) / 3 = 70 mmHg.
4. In the compensatory stage of shock, which clinical manifestation is commonly
observed?
A. Bradycardia
B. Anuria
C. Hypoventilation
D. Tachycardia
Answer: D
Rationale: During the compensatory stage, the SNS triggers tachycardia and
vasoconstriction to maintain cardiac output.
5. What is the first-line medication for a patient experiencing anaphylactic
shock?
A. Epinephrine
B. Methylprednisolone
C. Diphenhydramine
D. Dopamine
Answer: A
Rationale: Epinephrine is the gold standard for anaphylaxis as it causes bronchodilation
and vasoconstriction.
, 6. Which type of shock is characterized by a high Systemic Vascular Resistance
(SVR)?
A. Septic Shock
B. Hypovolemic Shock
C. Anaphylactic Shock
D. Neurogenic Shock
Answer: B
Rationale: In hypovolemic shock, the body increases SVR through vasoconstriction to
compensate for low volume.
7. A patient in septic shock remains hypotensive after a 30 mL/kg fluid bolus.
What is the preferred next step?
A. Administer Dobutamine
B. Initiate Norepinephrine
C. Administer Atropine
D. Start Nitroprusside
Answer: B
Rationale: Norepinephrine is the first-choice vasopressor for septic shock unresponsive to
initial fluid resuscitation.
8. Which shock state is unique due to the presence of bradycardia instead of
tachycardia?
A. Neurogenic Shock
B. Cardiogenic Shock
C. Septic Shock
D. Hypovolemic Shock
Answer: A
Rationale: Neurogenic shock results in the loss of sympathetic tone, leading to
parasympathetic dominance and bradycardia.
